How do we define the genetic makeup of an individual? Is it the genetic material found in each cell of that individual (that’s not entirely accurate; mutations and recombinatorial differences can lead to multiple genomes in one individual). And what about the genes carried by our microbiome? The... Read More
This episode: Amoebas in soil gang up on and eat much larger roundworms!

If the DNA sequence of a cell is like the operating system of a computer, then the smallest cellular OS has just been written. Called Syn3.0, it encodes everything needed to make a viable, autonomously replicating cell.
Mycoplasma is a genus of bacteria that are the smallest known free-living... Read More
Scientists and science educators now recognize the value in explaining what fields don’t understand, in addition to facts supported by years of experimental data. Citizen science projects, which emphasize accessibility of scientific technologies and methods for everyone, allow people without yea... Read More
Fecal transplants are increasingly being used for refractory Clostridium difficile and other gastrointestinal disorders. While fecal donors are screened for various infectious diseases, it is unclear whether viruses can in fact be transmitted during fecal transplants. Now a new study shows that ... Read More

The TWiP triumvirate solves the case of the Missionary in Kenya, and review the finding of a soldier caste in flatworms that parasitize snails.
Whether you’ve Google-searched “biofilm” to learn more yourself, taken courses covering the subject, or are deeply embedded in biofilm-related research, you’ve probably encountered a model similar to the one below, which represents biofilm maturation. In the current model, a biofilm begins with ... Read More
Today it is well known that viruses may contain DNA (poxvirus, mimivirus) or RNA (influenza virus, Zika virus), but for many years it was thought that genomes were only made of DNA. The surprise at finding only RNA in a virus is plainly evident in a 1953 letter from Harriett Ephrussi-Taylor to J... Read More
The molecular order of events is important in virulence, and a new paper published in the Journal of Bacteriology looks at the order of events necessary for bacterial toxin delivery to a host cell. Specifically, the authors looked at the assembly of Shiga toxin, produced by Shigella dysenteriae ... Read More
ASM aims to promote and advance the microbial sciences in a myriad of ways. In addition to promoting scientific education and discoveries, we also hope to engage the public with the diverse world of microbes! Last year, we held our first Agar Art contest, to highlight the often-overlooked beauty... Read More
This episode: A conversation with Audiommunity hosts about a rabbit virus that may help treat cancer while preventing the treatment from killing the patient!

Veintinueve profesores e investigadores de 20 universidades y centros de investigación van a colaborar para impartir el primer curso mundial online gratuito vía Twitter sobre microbiología. La iniciativa está coordinada y organizada por el grupo de Docencia y Difusión de la Microbiología de la S... Read More
In this month's episode of the science show This Week in Evolution, Nels and I discuss the evolution of butterfly wing patterns. In this study of Amazonian butterflies, the authors show that distinct patterns are a consequence of enhancer shuffling. Enhancers are DNA sequences that control trans... Read More
What kinds of microbes do you associate with hot springs? Maybe microbial mats? Thermus aquaticus and the discovery of Taq polymerase? Archaea, previously (and erroneously) thought to be strict extremophiles? Viruses may not be the first microbial subtype that springs to mind (pun intended) but ... Read More
Because of its safety, efficacy, and affordability, chloroquine remains the treatment of choice for all Plasmodium species, except in regions with chloroquine-resistant P. falciparum. Chloroquine-resistant protists are treated with combination therapy, which includes artemisinin-derived molecule... Read More
BOULDER - Key factors that can combine to produce a Zika virus outbreak are expected to be present in a number of U.S. cities during peak summer months, new research shows. Read More
Jean-Paul Latgé originally wanted to know if he could test the breath of patients with Aspergillus infections for volatile compounds produced by the fungus. His group at the Pasteur Institute in Paris thought this might be a new way of diagnosing fungal culprits like Aspergillus fumigatus that o... Read More
